Oh chemical pollutants I definitely recall - I was born in Camp Lejeune, where the USMC knowingly pumped a severely contaminated water supply to residents for years. Both my parents died of cancers attributable to the chemicals in that water a long time ago, I'm surprised it hasn't hit me . . . yet. On the other hand . . . salt is, you know, salt. Other than high blood pressure from ingesting too much I'm not aware of salt being considered a dangerous chemical to humans. Yes it is terrible for plants and overly saline water isn't going to be good for wildlife that needs fresh water but it's a tradeoff between that and having roads actually function. In the grand scheme of things the pollutants spewed out by the vehicles on those roads do way more damage than the salt put on those roads.
The killer eventually is in seams and where dirt accumulates - anywhere water is held against the steel reducing likelihood of evaporation. That is for longer term owners - people like me who tend to hang onto vehicles like grim death, lol.
That is interesting - definitely going to look into those products you mentioned. Maybe a similar product was Waxoyl? It used to be quite popular in the old Land Rover community. People would spray the inside and other areas of the steel frame rails. A poor mans solution was a more frequent spraying of diesel fuel on the undercarriage. Not sure how well that worked. You could end up with a bloody mess with sticky oil product and debris sticking to that, but would be better than rust all over.
The dealer I am thinking about going through says they dont rustproof or recommend it. They just protect vehicle with something called glass Sheid. I have always had my cars rusptoofed so a little confused.
